Summary of the invention
The objective of the invention is the deficiency that exists aspect mutual to above-mentioned existing three-dimensional xoncrete structure design of reinforcement software, provide that a kind of clear logic is succinct, friendly strong, dirigibility and the three-dimensional preferably xoncrete structure arrangement of reinforcement of completeness exchange method.
In order to solve the problems of the technologies described above, technical scheme of the present invention is such: a kind of three-dimensional xoncrete structure arrangement of reinforcement exchange method may further comprise the steps:
1) the main arrangement of reinforcement of structure cross section
Selected main arrangement of reinforcement member, the definition cutting planes cuts it, forms main arrangement of reinforcement cross section; Behind the selected main arrangement of reinforcement member, be the acquiescence cutting planes of (0,0,1) in normal direction of middle cage structure of main arrangement of reinforcement member, this cutting planes is illustrated with the rectangle plane of black.With cutting planes main arrangement of reinforcement member is cut, the cross section that obtains is as main arrangement of reinforcement cross section, and main arrangement of reinforcement cross section only is expressed as outline line, and outline line shows with white dashed line.If the needs of design are not satisfied in the main arrangement of reinforcement cross section of acquiescence; Straight line limit on then can selected member and with plane surface on its direction or the selected member and with the normal direction of its normal direction as new cutting planes; Can also drag cutting planes with the change cutting position, main arrangement of reinforcement cross section is with the variation real-time update of cutting planes.
2) expansion secondary reinforcement cross section
When the needs of design can not be satisfied in main arrangement of reinforcement cross section, the fixed one or more secondary reinforcement members of alternative cut them with the cutting planes that has defined, and form one or more secondary reinforcements cross section.Complete arrangement of reinforcement cross section has been formed in main arrangement of reinforcement cross section and secondary reinforcement cross section jointly; When selecting the secondary reinforcement member, select a plurality ofly if desired, then must pin Ctrl and select.The secondary reinforcement cross section is the same with the expression mode in main arrangement of reinforcement cross section, through the outline line demonstration of white dashed line; After new reinforcing bar group was created, its corresponding essential information was initialized to default value simultaneously, wherein, and with the positive integer of the minimum that do not taken by other reinforcing bar group under institute's metal elements acquiescence numbering as new reinforcing bar group
3) create the reinforcing bar group
Create new reinforcing bar group, selected main arrangement of reinforcement member in this reinforcing bar group ownership step 1), the essential information of the new reinforcing bar group of system initialization, essential information comprises numbering, type of action, material, diameter etc., as being distributed in the numbering under institute's metal elements for it automatically; The reinforcing bar group is the elementary cell of design of reinforcement; The reinforcing bar group has unique numbering under institute's metal elements; All reinforcing bars under the same reinforcing bar group have unified type of action, element type, material, diameter, remarks etc., and all these attributes are together with the essential information of numbering as the reinforcing bar group;
4) reinforcing bar group essential information is set
Initial value to each attribute in the reinforcing bar group essential information is confirmed, carries out corresponding modification and adjustment by designing requirement;
5) create sub-reinforcing bar group
Can comprise a plurality of variform sub-reinforcing bar groups under the reinforcing bar group, and the shape of the reinforcing bar under the same individual sub-reinforcing bar group is same or analogous.This step is created a new sub-reinforcing bar group under the reinforcing bar group that step 3) generates; The minimum unit that described sub-reinforcing bar group is the reinforcing bar moulding, all the reinforcing bar shapes under the same sub-reinforcing bar group are same or similar, and a plurality of sub-reinforcing bar groups can be arranged under the reinforcing bar group; The muscle face normal direction of the reinforcing bar under the described sub-reinforcing bar group, i.e. the normal direction on the of living in or determined plane of the center line of reinforcing bar is the normal direction in the main arrangement of reinforcement cross section of constructing in the step 1);
6) main part of antithetical phrase reinforcing bar group is carried out the sketch moulding
The main part of reinforcing bar is meant the anchoring and the remaining afterwards part of crotch of removing two ends.This step is on the good arrangement of reinforcement cross section of structure; Each section by dual mode antithetical phrase reinforcing bar group main part is carried out moulding; A kind of is to pick up the limit in arrangement of reinforcement cross section as about beam geometry; Corresponding lengths of rebar is parallel with this limit, cross section; Another kind is to add free section, by relevant parameter it is carried out constraint definition;
Described through adding the mode of free section constructor reinforcing bar group main paragraph, the form of two kinds of free sections is provided: straight section and arc section; Relevant parameter except the constraint through the limit, cross section makes main paragraph and this limit, cross section is parallel, also need be set as the mode of the sub-reinforcing bar group of constraint geometrical construction main paragraph in described limit through picking up the arrangement of reinforcement cross section, comprises following:
(1) length, the i.e. length of main paragraph;
(2) guiding, guiding has forward and reverse two values, and default value is a forward;
If first main paragraph is then appointed and got a vector parallel with the limit, cross section, check its x, y, z component value successively; Current component value is 0 o'clock, continues the next component value of inspection, when current component value is positive number; Stop to check and being left intact; When current component value is negative, with this component take absolute value and stop the inspection, the vectorial determined direction after the processing is the forward of main paragraph.The opposite direction of forward is oppositely.
Not so; If the limit of previous main paragraph through picking up the arrangement of reinforcement cross section is as the constraint geometrical construction; Then turn to interior direction one side of the corresponding component surface in the limit, about area of beam of last main paragraph to be forward; If previous main paragraph is constructed through the mode of adding straight section, then turn to the normal direction in arrangement of reinforcement cross section and multiplication cross gained direction one side of moving towards of last main paragraph to be forward, if previous main paragraph is constructed through the mode of adding arc section; Then current main paragraph can only be along the terminal tangent line bearing of trend of arc section, and the guide securement of current main paragraph is a forward.
(3) with reference to edge, with reference to edge inner edge, center line, three values of outer rim are arranged, if the type of action of affiliated reinforcing bar group is stirrup or lacing wire, then the default value with reference to edge is an inner edge, otherwise is outer rim.
Confirm the tolerance benchmark edge face of the distance that reinforcing bar is surperficial with making an appointment with area of beam limit institute counterpart member with reference to edge; With parallel plane, area of beam limit institute counterpart member surface can be tangent from both sides and lengths of rebar approximately; The phase tangent plane of direction one side is outer edge surface outside the counterpart member surface, and the phase tangent plane of opposite side is inner edge surface; Wherein, approximately the pairing component surface in limit, area of beam be with step (1) in the cutting planes confirmed intersect the component surface that forms this limit, pact area of beam.
(4) distance value, the distance between the reference edge of the lengths of rebar component surface corresponding with about limit, area of beam, the default value of distance value is 1, is protective layer thickness in conjunction with the default value of parasang, the distance of promptly giving tacit consent to is 1 times a protective layer thickness.
(5) parasang, parasang have mm and two values of protective layer thickness, and the default value of parasang is a protective layer thickness.
(6) protective layer thickness, protective layer thickness are the segment distances that component surface inwardly keeps, and this distance is interior generally should not arrange reinforcing bar, with the destruction of protecting reinforcing bar not receive external environment condition.The all corresponding protective layer thickness in each surface of member, revise this value then with this surface as about beam geometry object all possible influenced.When a component surface was selected as about beam geometry for the first time, the protective layer thickness of its acquiescence was 50mm.
Simultaneously, in this step, the main part of described sub-reinforcing bar group; Its first main paragraph can not be arc section; Be first main paragraph or the limit through picking up the arrangement of reinforcement cross section as the constraint geometrical construction, at this moment, its trend; Promptly the direction from the head end to the end can be confirmed through about limit, area of beam and correlation parameter; Perhaps construct through the mode of adding straight section, at this moment, its trend need be set, the trend of acquiescence is inspection (1,0 successively; 0), (0,1,0), (0; 0,1) three vectors, find with main arrangement of reinforcement method of section to uneven first, then with the vector of this vector projection gained to the arrangement of reinforcement cross section; Simultaneously, last main paragraph can not be arc section.Further, the main part of described sub-reinforcing bar group, free section of can not add two arc section forms continuously.
Straight section in the described free section retrains structure through following three parameters:
(1) length, the length of promptly corresponding main paragraph, default value is 1000mm;
(2) guiding, guiding has forward and reverse two values, and default value is a forward;
If first main paragraph, then guide securement is a forward; Not so; If the limit of previous main paragraph through picking up the arrangement of reinforcement cross section is as the constraint geometrical construction; Then turn to interior direction one side of the corresponding component surface in the limit, about area of beam of last main paragraph to be forward; If previous main paragraph is constructed through the mode of adding straight section, then turn to the normal direction in arrangement of reinforcement cross section and multiplication cross gained direction one side of moving towards of last main paragraph to be forward, if previous main paragraph is constructed through the mode of adding arc section; Then current main paragraph can only be along the terminal tangent line bearing of trend of arc section, and the guide securement of current main paragraph is a forward.
(3) deflection angle, deflection angle are the angle of terminal bearing of trend of trend and the previous main paragraph of current main paragraph.
If first main paragraph, then deflection angle is fixed as 0; If previous main paragraph is constructed through the mode of adding arc section, then current main paragraph can only be along the terminal tangent line bearing of trend of arc section, and the deflection angle of current main paragraph also is fixed as 0; Under other situation, the span of deflection angle is (0,180).
Arc section in the described free section retrains structure through following three parameters:
(1) crooked internal diameter, i.e. the inner edge diameter of arc section.
(2) guiding, guiding has forward and reverse two values, and default value is a forward.
If the limit of previous main paragraph through picking up the arrangement of reinforcement cross section is as the constraint geometrical construction; Then arc section is forward to the interior direction one lateral bending song of the corresponding component surface in the limit, about area of beam of last main paragraph; If previous main paragraph is constructed through the mode of adding straight section, then arc section is forward to the normal direction in arrangement of reinforcement cross section and the multiplication cross gained direction one lateral bending song that moves towards of last main paragraph.
(3) angle of bend, the i.e. corresponding central angle of arc section.
In this step; If clash between the constraint of different subjects section; There is priority between the then different constraints; Limit through the arrangement of reinforcement cross section has the highest priority to the parallel constraint that main paragraph carries out with interior the constraint through the deflection angle that retrains and be directed against free straight section of bending that relevant surface distance retrained and be directed against free arc section, and next is the angle of bend constraint of free arc section, and length constraint priority is minimum.For example; If after a free straight section, constructed another main paragraph as constraint through the limit of picking up the arrangement of reinforcement cross section; But give this length constraint that free straight section is set and it is connected required physical length does not wait with next section; At this moment, can not regulate the relevant parameter of limit, cross section constraint of next section, but the length constraint of regulating free straight section automatically is to eliminate conflict.
7) end of antithetical phrase reinforcing bar group is provided with
By the needs of design, the locating information at antithetical phrase reinforcing bar group main part two ends is made amendment and is adjusted, and is used for the end is retrained the limit, cross section or the summit, cross section of location like replacing.Simultaneously, can select at two ends respectively to add anchoring and crotch, relevant attribute is set; The location at wherein said antithetical phrase reinforcing bar group two ends is undertaken by following mode:
(1) for head end; If first main paragraph is free straight section, then a summit with the arrangement of reinforcement cross section positions as constraint, at this moment; Must be in the distance that is provided with on the both direction between head end and the summit, location; A direction is the trend of first main paragraph, and another difference of moving towards for the normal direction in arrangement of reinforcement cross section and first main paragraph is taken advantage of the direction that obtains, the anchor point of acquiescence be main arrangement of reinforcement cross section upwards be in a rearmost summit along walking of first main paragraph; If as constraint, then head end positions as constraint with a limit in arrangement of reinforcement cross section first main paragraph, at this moment, the distance between head end and the gulde edge must be set with the limit in arrangement of reinforcement cross section.
(2) for end; Length constraint through last main paragraph enough positions it; If but be inconvenient to confirm the length of last main paragraph, a limit also can selecting on the arrangement of reinforcement cross section positions end as constraint, and the distance between end and the gulde edge is set.Be defaulted as through length constraint and position.
Simultaneously, in this step, obstacle and two kinds of forms of penetrate are dodged in described anchoring; Dodge the anchorage length that obstacle stretches out and sets for corresponding end, if by certain limit, bar arrangement of reinforcement cross section, also promptly the corresponding component surface in this limit stops in the process; And the still not enough anchorage length of development length this moment then changes direction, continues to extend along this limit, arrangement of reinforcement cross section; Inflexion point is called anchoring and divides the distance of cloth cover to confirm through reinforcing bar and this counterpart member surface, limit, obstacle cross section are set; Penetrate does not consider then whether reinforcing bar is stopped by component surface that anchorage part stretches out always.If its form of anchoring of adding is for dodging obstacle; Corresponding guiding attribute then also need be set; When deflection appears in anchoring; The guiding attribute confirms it to which lateral deviation changes, and guiding has forward and reverse two values, and wherein interior direction one side to the limit, about area of beam of adjacent body section counterpart member surface is a forward.
In this step; Have only first main paragraph to construct as constraint with the limit in arrangement of reinforcement cross section; Could add the head end anchoring; Have only last main paragraph to construct as constraint and the end of main part positions as constraint with the limit in arrangement of reinforcement cross section, could add terminal anchoring with the limit in arrangement of reinforcement cross section.
Further, the crotch described in this step comprises crooked internal diameter, angle of bend, straight length and four attributes that lead.Wherein, Guiding confirms that crotch is bent to which lateral bending; Guiding has forward and reverse two values, if adjacent lengths of rebar has corresponding limit, about area of beam, then interior direction one side to this counterpart member surface, limit, pact area of beam is a forward; Not so, forward is the normal direction in arrangement of reinforcement cross section and the side that crotch corresponding end bearing of trend multiplication cross gained direction is confirmed.For the sub-reinforcing bar group of new establishment, though reinforcing bar does not also carry out actual layout, through on the arrangement of reinforcement cross section, introducing an example reinforcing bar, any design action of being carried out in these steps still can obtain real-time feedback on the example reinforcing bar.
8) arrange sub-reinforcing bar group
Confirm that as the position constraint at interval two ends one or more layouts are interval through summit on the paired pick-up member or the plane surface parallel with the arrangement of reinforcement cross section; Each is set arranges interval bar spacing; Then with the shape sketch of the reinforcing bar that structure is good on the arrangement of reinforcement cross section as mould; Through corresponding translation transformation, accomplish the layout of whole sub-reinforcing bar group; Describedly carry out translation transformation as mould with the shape sketch; Be specially; At first for each non-free arc section confirm the distribution planar process to, with the section of limit, arrangement of reinforcement cross section as constraint structure, its distribution planar process is to being the outer direction on limit, area of beam counterpart member surface approximately; And for free straight section; Its distribution planar process is to the direction that is this free straight section trend and arranged direction multiplication cross gained, and then, the translation transformation direction of the node between any two non-free arc sections can be confirmed as the direction of their corresponding distribution planar processes to the multiplication cross gained.Arranged direction can be set to arbitrarily and the arrangement of reinforcement method of section to the off plumb direction, be defaulted as the arrangement of reinforcement method of section to.Bar space is controlled on arranged direction.
9) the cloth postpone of a sub-reinforcing bar group of completion; Can get back to step 5); Based on working as the good arrangement of reinforcement cross section of front construction under current reinforcing bar group, begin to dispose a new sub-reinforcing bar group, also can get back to step 3); Begin to dispose a new reinforcing bar group based on current arrangement of reinforcement cross section, perhaps directly withdraw from whole mutual.
In the interaction flow traveling process; Except the design of carrying out the next flow process step that does not get into successively; Also can get back to the flow process step of having passed by before, as required relevant design item carried out instant editor and modification, but can not skip also no show and the flow process step that be necessity; Promptly getting into certain flow process before the step, the necessary flow process step that is in its front must be confirmed to accomplish.
The present invention through control provides the arrangement of reinforcement of guiding mutual to the designer based on flow process, makes the logic of reciprocal process more clear and orderly through after adopting said method; Simultaneously, through introducing the example reinforcing bar on the arrangement of reinforcement cross section, make any one design action in the reciprocal process can both on model, obtain instant feedback, the observation design result that the designer can be real-time is in time found mistake, and design process is also more directly perceived; In addition, introduce through adding the mode of free section distributing bar main paragraph, thus provide to the special shape reinforcing bar flexibly, complete relatively sculpting method; At last; Do not provide and need rotate the structure model; Through hiding the method for block surface step by step to being blocked and picking up for how much; Guarantee the current design thinking not because of the change of view direction is interfered, also avoided, make picking up of how much of members more efficient and easy big component model, inconvenience when the complex component model is rotated.
